GPA for Transfers

I’m considering transferring to Barnard as a junior and was just got my semester grades for the spring. I took 20 units first semester and 21 second semester with a cumulative GPA of 3.78. That seems fairly low compared to others on this forum who apply as transfers. I’m in a sorority, wrote for student media, and have gotten very involved in my major’s department. How else can I increase my chances?
